Everyone sees themselves as the hero of their own story, even if they are the villain of someone else’s. One-dimensional villains may suit simple minds, but to add deep nuance and rich emotional experiences to your story, write a complicated, relatable villain. Don’t pull any punches—clearly justify their motivations with an impactful opening scene. The worst villains are negative, power-hungry, and one-dimensional—avoid these traits like the plague. No matter how you’ve written the antagonistic force in your story, it must be understandable and strongly argued.
